TARK, OF PHILADELPHIA, PENNSYLVANIA, ASS IGNOR TO LINK-BELT COMPANY, OF PHILADELPHIA, PENNSYLVANIA BEARING Original application filed June 18, 1929, Serial No. 371,876. Divided and this application filed November 21,'1930. Serial No. 497,291.

This invention relates to a bearing to be used in sewage settling tanks, where it will be submerged in liquids carrying putrescible solids and colloidal matter in suspension. The purpose of the invention is to provide a bearing on which settable solids and colloidal matter, commonlyknown as sewage sludge my copending application Serial No. 371,876,

filed June 18. 1929.

In th drawings showing several forms'of the invention Fig. 1 is an elevation of one form taken parallel to the axis of the bearing,

Fig. 2 is an elevation taken at right angles to Fig. 1,

Fig 3. is an elevation of a solid peak cap bearing,

Fig. 4 is a plan of the bearing shown in Fig. 3.

Fig. 5 is an elevation'of a standard bearing enclosed in a sheet metal casingto serve the same purpose as the special bearing shown in Fig. 1, and. v

Fig. 6 is a plan of the bearing shown in Fi 5. j

The bearing shown in Figs. 1 and 2 consists of-a base member 1 and cap 2, both lined with bearing metal 3 to receive the end of a shaft 4. In accordance with my invention the cap 2 has a peaked roof 5 making such an angle with the horizontal that the sus ended solid matter which will be encountere in the particular place in which the bearing is to be located will not remain on thecap, but will continue its way to the bottom and so be removed.

Figs. 3 and 4 show a solid bearing 6 the sides of which form a peaked roof in accordance with my invention.

- Figs. 5 and 6 show a standard bearing 8 over which is placed a peaked cap 9. The cap is/secured to the base of the bearing by screws 10. The sides 11 of the cap are at such an angle that solids cannot settle on 1 them.

I have found that an angle of is sufficient to prevent the lightest solids carried by sewage from gathering on the cap.

My invention is susceptible to various modifications falling within the scope of the following claims.

I claim: A

1..In a settling tank adapted to receive liquids carr ing putrescible solids in suspension; a sha t; a bearing for said shaft; said bearing being completely enclosed, except forthe shaft aperture, by walls which are either sharply inclined or vertical, and walls which face downward; said sharply inclined walls terminating at their lower edges only at the lateral boundaries of the bearing;

. whereby said bearing is without upwardly facing horizontal surfaces or pockets on which or in which solids could accumulate. 2. A bearing for use in tanks containing pension; said bearing being completely enclosed, except for the shaft aperture, by walls. which are-either sharply inclined or vertical, and walls which face downward; said sharply inclined walls terminating at their lower edges only at the lateral boundaries'of the bearing; whereby said bearing is without upwardly facing horizontal sur- .liquids carrying putrescible solids in susfaces or pockets on which or in which solids could accumulate.

3. A bearing completely enclosed, except for the shaft aperture, by walls which are either sharply inclined or vertical, and walls which face downward; said sharply inclined walls terminating at their lower edges only at the lateral boundaries of the bearings; whereby said bearing is without upwardly facing horizontal surfaces or pockets.

The foregoing specification signed at Philadelphia, Pennsylvania, this fifteenth day of November, 1930.
